THOUSAND OAKS, Calif. — An armed man dressed in black opened fire late Wednesday night inside a crowded country and western dance hall in Thousand Oaks, Calif., killing at least 12 people, including a sheriff’s deputy who had responded to the scene. The gunman was also dead.
The shooting came just over a year after 58 people were killed at a country music festival in Las Vegas
when a gunman opened fire from a high-rise hotel room. There was an eerie parallel between the two shootings as some of the same people who emerged from the bar, the Borderline Bar & Grill, described having survived the shooting on the Las Vegas Strip.
Witnesses recalled a chaotic scene at the bar, which was filled with hundreds of people, many of them college students: A gunman opening fire, first at a security guard, as patrons dropped to the dance floor, hid under tables and broke windows to escape.
